IMPROVEMENT IN HORSE HAY-RAKES.

Specification forming part of Letters Patent No. 119,669, dated October3, 1871.

To all whom it may concern:

Be it known that I, GEORGE SWEEr,of Dansville, in the county ofLivingston and in the State of New York, have invented certain new anduseful Improvements in Hay-Rakes; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangementof a horse hay-rake, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side elevation of my rake with one of the driving-wheelsremoved. Fig. 2 is a plan view of the axle with the rake and its attachments. Fig. 3 is a front view of one of the brakes.

A represents the axle, having the drivingwheels B B mounted upon itsends. In rear of the axle A, and parallel with it, runs a bar, 0,notched on its upper'side at regular intervals. This bar is connectedwith the axle by suitable blocks or other supports, and the rake-teeth DD are coiled around the same, one in each notch, and the inner or upperends of the teeth are inserted in the rear side of the axle. E Erepresent the thills or shafts, attached to the axle by means of jointsor hinges a a, and upon said thills, near the rear ends, are securedbars or boards G G. On these bars, near one end, are secured two bars, HH, which full at right angles with the axle, and between which the frontend of the lock-lever is pivoted. This lock-lever consists of threeparts, I, I and I The part I is pivoted at its front end between thebars H H, and its rear end is provided with a longitudinal slot, andalso with teeth or corrugations on its upper side. The front end of thepart I is made of the same width as the part I, and provided with teethor corrugations on its under side as well as with a longitudinal slot.By means of a bolt and thumb-nut, b, passing through said slots, thesetwo parts may be firmly joined together, and lengthened or shortened atwill, according to circumstances. The rear end of the part I is pivotedin the forked front end of the part 1 through the rear end of which ashaft, J, passes. This shaft runs above and parallel with the axle A,and has its bearings in suitable boxes d (I attached to the axle A. Uponeach end of the shaft J is a small crank, e, to which a pitman or rod,f, is attached. The upper end of this rod or pitman is provided withscrew-threads, and a brake-block, K, is adjusted upon the same by meansof nuts h h. This brake-block extends above the wheel, and is, on itsunder side, near the inner end, provided with a socket, 7c, fitting overthe upper end of a standard, m, attached to the upper side of the axleA. Upon the shaft J is further secured a lever, L, having a cam, z, uponits lower end below the shaft, which cam, when the lever is thrownforward, presses down upon the rear end of a pivoted bar, n. The frontend of this bar then presses upward upon the lock-bar, immediately underor near the joint between the parts I and 1 It will thus be seen that bythrowing the lever L forward the brake-blocks K K are pressed down wardupon the periphery of the driving-wheels, and, at the same time, thejoint of the lock-bar or lock-lever is broken, the former causing andthe latter allowing the axle to turn, and thereby unload the rake. Bythrowing the lever L backward again the brake-blocks are released fromthe wheels and the teeth fall back into position for raking. Thismovement locks the lever or lock-bar, which holds the teeth firmly totheir work until again released by a forward movement of the lever L, asbefore described.

I am aware that the application of brakes to the wheels of a horsehay-rake for unloading the rake is not new 5 hence I do not wish to beunderstood as broadly claiming such to be my invention.

Havingthus fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The combination, in a horse-rake having wheels B B and axle A, of aseries of rake-teeth, D, attached to a cross-bar, (l, rigidly connectedparallel with and in rear of the axle, shaft J with cranks e e and leverL, rods ff, guide-standards m m, and brake-blocks K acting on theperiphery of the driving-wheel for unloading the rake, all substantiallyas herein set forth.

2. The lock-lever, composed of the three parts a I, I and 1 when saidparts are construeed and hereunto set my hand and seal this 17th day ofarranged substantially as and for the purposes August, 1871. herein setforth. GEORGE SWEET. [L. s.]

SwThe combination of the lever L with cam 41 and pivoted bar at forbreaking the joint of the Witnesses: look-lever, substantially as hereinset forth. '1. B. GRANT,
